Control Transformers

MSI Control Transformer

Control transformers are used to step down supply voltages like 480 V, 380 V, 220 V and others to a lower, safer voltage for control circuits and other low power devices, such as relays. They also offer a means of isolation for these sometimes sensitive devices.
